1o the cap upon the nozzle, =this lever resting substantially parallel with the nozzle when in its locked position.

an exceedingly simple butat thesame. time eflicient construction of lock-or seal for the lever, which must be severed or broken-m order to initially remove the cap fromthe nozzle. By means of this lock or seal the can 'be assured. Inasmuch as these caps are nerally applied to'the'nozzles by machinery 1n rapid succession the seal must be of such over'the nozzle and cap This band or seal is; of such Width that when resting upon the 'top of the can it will extend up over and embrace-the: lower. end of the locking lever 4 of thecap and it will be understood that-the band after it has dried or cured and contracted will be of such size as to snugly embrace the nozzle or neck and lever and when g so contractedcannot he slipped over the cap and. will prevent its removal over the to of the ca ..'-The width of the band also len s itself to t c. printing of any cautionary. legend The object of this invention is to provide.

or'advertising matter, if so desirable. The bands-may be'slipped over the nozzle while wet'and'allowed to dry thereon and when dry they contract and harden or set and firm- 1y hold the lever 4 against the nozzle. It

will now be clear that'it will be impossible to genuineness of the contents of the receptaclei remove the cap without damaging or breaking the seal. Suitable indicia or advertising matter may be placed on the seal, for example Contents guaranteed if seal is unv constructionthat it can be rapidly applied, broken, or'words to thatefiect.

to the nozzles. as Another object of the invent1on 1s to provide a seal which is well adapted for all types of removable closures whether they be machmeafiixed closures or hand applied closures.

With these objects in view the nvention consists in the novel features of construction as will be hereinafter more hilly de-.

scribed and set forth in theappended claims.

. In the drawings forming a part oi the 86 ecifica tio'n' Fig. l is a perspective view of a ling can nozzle with my seal attached thereto; and Fig. 2 is a perspective new of theseal removed from the nozzle. L r

In Fig. 1 the numeral 1 desi ates a conventional filling having e usual discharge nozzle- 2 and a seahng closure 3 adaptedtobelockedinplacebyacamlever i. This form of closure is well known 1n the art and needs no explanation.

I Manufacturers of standard commoditiesdo not wish their containers to be tampered w th or refilled with an inferior product and sold as the original package. In order to prevent tampering with or unauthorlzed removal of 5 the contents oftbe' container I have rovided a seal 5 which surrounds the nozz" e 2 and cam lever 4 as clearl shown in F1g. 1. The seal or band 5 is a co ulose product and when wet or green is large enough to-be slipped .-The until'the bands are shrunk. Cans or bottles can be packed immediatelyafter the bands are applied. In case the seal is applied to a bottle the bottles areusually labeled before the bands are-applied. Cans as a rule are litho aphed and if they are to be labeled the abels are applied. before the seal is ap lied.

t will'snow' be clear that I have provided a seal which will accom lish the ob ects of the invention asy'hereinbe ore stated and that I have provided an effectual means for preventing unauthorized use of ori a1 containers to the'detriment of the origmal vendor.

It is to beunderstood that -I do not limit myself to a cellulose seal as any product having -;similar qualities may be used, I further wish it to-be understood that my seal is applicable to all forms of containers in operation of scaling is not delayed which it may be desirable to seal the cap or closure. on the container. v Having thus described my invention, what I claim 1s:--

1. A closure seal. comprising an endless band adapted to be placed about the neck or nozzle of a containerand'theleyer of a neck of container and prevent movement of said lever without breaking contracted seal- .ing band.

tightly upon contraction upon drying or" curing for the purpose specified.

3. The combination with a. nozzle and cap applied thereto, said ca having a lever adapted to rest inparalle relation w1th the nozzle when the cap is fastened upon said nozzle, of a band applied in uncured or undried condition to surround said nozzle and lever and adapted to contract upon curing or drying to securely hold said lever.

4. The combination with a container of a cap applied thereto, said cap having a lever adapted to rest in parallel relation with the side of the container when the cap is locked thereon, and a continuous band applied in moist and extended condition to surround said container and lever and adapted to contract upon drying to securely hold said lever.

- In testimony whereof, I hereunto afiix my signature.
